Researchers Map the Internet

[AP] It took two months and nearly 3 billion electronic probes for researchers to create a map of the Internet. Now comes the task of making sense of their data – and figuring out what they missed.The Internet census comes from the University of Southern California’s Information Sciences Institute in Marina del Rey, Calif.Over two months, ISI computers sent queries to about 2.8 billion numeric “Internet Protocol,” or IP, addresses that identify individual computers on the Internet.Replies came from about 187 million of the IP addresses, and researchers used that data to map out where computers exist on the Internet. At one dot per address using a typical printer, the resulting map was about 9 feet by 9 feet. The top finally was taped onto the 8-foot-high ceiling.
